Prof Laurent Frantz of the University of Oxford and Zooarchaeologist Prof Angela Perri of Durham University put their genetic study findings on ancient dogs of America; Prof Frantz suggests that the rate of genetic mutation indicates ancient North American dogs and ancient Siberian dogs shared a common ancestor some 16,000 years ago, or about the time when humans were migrating into North America. Prof Perri says that dogs may have travelled to the New World with humans, or they may have crossed the land bridge from Siberia into North America on their own at a later date, but before the land bridge disappeared some 11,000 years ago. The first North American dogs, according to this study, were likely wiped out by diseases brought to the New World by the dogs of European explorers.

In the ancient world, there was a tribe in the name of Dog , and also a star in the sky was called Dog Star. It was very peculiar as the name of their settlement went by the name of the tribe; the interesting geographical factor related to this tribe’s settlement was that there were two settlements called Kukura, and they were very close to Jerusalem, seat of worship of Yama, the God of Death. Scientists doing genetic study on dogs and their migration cannot avoid this point. The Dog Star was then helping the mariners to reach their distant destinations.

Prof Perri’s view on the land bridge’s disappearance some 11,000 years ago is far away from truth; Ptolemy’s maps will help to dispel this incorrect idea.
